High quality new data on the asteroid mass and volume were produced in the last years from both extra-atmospheric instruments and the groundbased high-performance telescopes. This paper presents a synthesis of these results in terms of the asteroid density, taking into account several techniques, and the possible correlation of the density through the taxonomic system.
The important conclusion is that M-type asteroids seems to have an unexpected low density, which cannot be explained by the present mineralogy assumed by the comparative mineralogy.
